接收到的错误数据包数 Packets received errors
Oerrs：从接口传输的错误数据包量。
Oerrs: The amount of error packets transmitted from the interface.
在所有情况下，都要寻找比较高的错误数据包、重新传输或丢失数据包传输数量，这些都说明网络忙。
In all cases, you are looking for a high level of error packets, retransmissions, or dropped packet transmission, all of which indicate that the network is busy.
尽管这项技术在很多方面已经有了改进，但协议将信息进行分割成数据包，并帧听传输过程中错误的方法却是公认的。
It has been improved in many ways, but the way in which the protocol breaks information into packets and then checks for errors in their transmission is still recognisable.
